Answer:
I believe the best answer would be a(n) investment.
Equation A simplifies to 0 = 0. It is always true.
Equation B simplifies to 1 = -1 for a ≠ 0. It is never true.
Equation C simplifies to 2a = 0. It is true only for a = 0.
Equation D simplifies to 2a = 0. It is only true for a = 0.
The equation that is true for all values of "a" is ...
A. Equation A
The answer is
![- \frac{1}{6}](https://tex.z-dn.net/?f=-%20%5Cfrac%7B1%7D%7B6%7D%20)
This is because a negative exponent creates a fraction (not a negative number) so 6^-1 becomes 1/6, but the answer is negative because the negative sign is outside the brackets. <span />

Step-by-step explanation:
can you give me brainlist
let x=width, so 2x=length
area = area __ (x+3)(2x+3) = (x)(2x) + 54
2x^2+9x+9 = 2x^2+54
subtracting 2x^2+9 __ 9x = 45
dividing by 9 __ x = 5
